26 Claims. (0!. 214-17) This invention relates to dictation machines. and more particularly to control means therefor In dictation machines, particularly the type used to record the dictation, there is provided a stop-and-start control (usually remote from the machine) and another control by the manual operation of which the machine may be conditioned for either recording or reproducing, or to be neutral, and this control, herein reierred to as no a sound-box control or conditioning control means, may be manually shifted at will by the operator so that he can record or listen to matter already dictated. 1n theusual dictation machine construction, the sound-box cannot record when the control device is in neutral or reproducing position, and hence, if the operator inadvertently dictates to the machine while the control device is in neutral or reproducing position, no useful record would be made.

should the operator discover that the machine is not conditioned to record shortly after he has :started dictatingthe mistake canbe easily rem- .the regular construction of the-machine to serve edied, but it is extremely embarrassing and annoying to find, after one has dictated for a long corded, for, as iswell known, after a matter has once been dictated or spoken, it is seldom that a person can again repeat the thoughts with the same force andstyle. I f

Fin-order to obviate this vantage, means have been proposed heretofore whereby the startand-stop control may be rendered inoperable when the sound-box control is in neutral or reproducing positiomthereby necessitating manual operation of an auxiliary control provided on the machine to start and stop the e when reproducing.

An object of the present invention is to further obviate this disadvantage and to so facilitate operation of the 'macethat operation cl an auxiliary control during reproduction is non Accordingly, means are provided by this invention to prevent operation or the usual start-andstop mec t m when the sound-box control is in neutral position and to automatically start the machine for reproduc when the sound-box control is moved to reproducing position. To further avoid incorrect use ol the machine, the present invention also provides means to move the sound-box control automatically out of reproducing position into neutral position in which, as stated, the stop-and-start control is inoperable when the operator releases the control. Thus it wlll be seen that the operator cannot inadvertently, dictate, either while the control is in re time, that the matter so dictated has not been reproducing position because the sound-box does not remain in that position when released, or

while the control is in'neutral position because he cannot operate the start-and-stop. control.

These features are extremely advantageous; 00 for, by their provision, the operator can give more time and thought to dictation and is not required to cautiously or thoughtfully operate the machine; the operations are performed subcon sciously by him, or else he is prevented from doing 05 that which he should not do.

A feature of the present invention is the pro vision of means whereby the sound-box may be 0 conditioned by the operation of a lever; the position of which is fixed relative to the machine, 70, thus further facilitating the operation of the machine, for, in the usual construction, the operator must more closely observe the machine because the control lever is not fixed relative to the machine but is mounted on the sliding car- 75,

e. t Another ieature is the utilization of parts of dual purposes. A further feature is the provision of means so controlled by the switch lever whereby the startand-stop device is rendered inoperable when the switch lever is in position to render the motor for the machine inoperative.

Other objects and advantages will hereinafter 35 pp ar.

' ducing position.

The dictation machine shown in the accompanying drawings comprises a main frame 12, having standards 13 and 14 supporting upper and lower guide rods 15 and 16 upon which a sound-box carriage 1'7 is adapted to slide to and fro longitudinally of the frame to carry a sound-box 18 over the surface of a record 19, mounted on a record-support 20 having a shaft 21 rotatably mounted in a housing 22 forming part of the main frame 12.

Longitudinal movementof the carriage 17 and sound-box 18 over the record surface is accomplished by a rotating feed-screw 23 engaged with a feed-nut 24 carried by the carriage 1'7.

The sound-box 18 is mounted for upand-down movement, to accommodate records of different diameters or to follow irregularities of the recordsurface, on trunnions 25 carried by a supporting sleeve 26 which in turn is pivotally mounted by a rod 27 in a tube 28 which is slidably mounted in a holder or casing 29 secured to the carrlage 17 by screws 30. The tube 28 is longitudinally movable in the casing 29 so as to bring a recording stylus 31 or ,a reproducing stylus 32 into position to engage a record, or to cause both styli to be raised from the record when the sound-box 18 is in an intermediate or neutral position, as shown in Fig. 2, where it is supported by a lug 33 engaging a stud 34 carried by the casing 29. Hence, when the sliding tube 28 is moved longitudinally in the casing 29, ei-

. ther recording stylus 31, reproducing stylus 32,

or neither styli is in engagement with the record surface, depending upon the position of the sliding tube 28 in the casing 29.

For the purpose of moving the sound-box 18 to any of the positions referred to, the slide 28 is connected by a link 35 to the lower end of a control lever 36 whose upper and exposed end is adapted to be moved by hand. As shown in the drawings, the control lever 36 pivots about the axis of the feed-screw 23. This control lever 36 may be shifted from the neutral position shown in full lines in Fig. 2 forwardly to the dictating position, or rearwardly to the reproducing position, as shown by dotted outline. In the neutral position shown, the feed-nut 24 is, as usual, moved downwardly out of engagement with the feed-screw 23 so that the carriage is free 1 for movement longitudinally of the record to any desired position.

Sound, as for instance matter of dictation, is collected and transmitted to the sound-box 18, by means of a speaking .tube 37 connected with the casing 29 for the sound-box slide 28 at one end, and having at its other end a handle 38 provided with a mouthpiece 39, as shown in Figure 2.

In using the machine, the operator grasps the handle 38 and holds the mouthpiece 39 adjacent his lips, so that, as he dictates, sound is received by the mouthpiece 39 and passes through the tube 37 to the sound-box 18 where it actuates the recording stylus 31 which, in turn, cuts helical sound grooves on the record surface while the record-support'20 rotates and the carriage and sound-box moves over the record surface.

Conversely, when the sound-box is in reproducing position and the reproducing stylus 32 engages the record'while the record-support rotates and the carriage moves, the diaphragm vibrates and produces sound which is transmitted through the tube 37 to the mouthpiece 39 which the operator then holds at his ear.

In the construction shown, movement of the carriage 17 and rotation of the record support 26 is effected by means of a driving device comprising a rotating pulley 40 which is loose on the mandrel shaft 21 but which can be operatively connected therewith by a clutch 41 actuated by means hereinafter described. The pulley 40 is driven through a connecting belt 42 by an electric motor 43 supported on the under side of the flatplate portion of the main frame 12. Rotation of the feed-screw 23 for moving the carriage is accomplished by means of any suitable gear train, such as is indicated in dash and dot circles in Fig. 2 and by the number 44 in Fig. 1, and which is interposed between the feed screw 23 and the rotatable mandrel shaft 21.

In order to control the starting and stopping of the dictation machine so that, during pauses in dictation, the machine will not operate and unnecessarily use up space on the record, the usual clutch mechanism is provided to connect the driving pulley 40 with the operating mechanism of the machine, including the mandrel-shaft 21 and feed-screw 23. This clutch control mech' anism comprises a grooved collar 45 mounted within the housing 22 and shifted longitudinally of the shaft 21by a shifting yoke 46 having upstanding arms 47 provided with pins which enter a groove-48 of the collar 45. The yoke 46 is pivotally mounted on a stud 49 carried by the housing 22 and is so arranged that, when operated, it causes the collar 45 to be moved longitudinally to move a related clutch member 50 into or out of engagement with the teeth 51 on the pulley 40 to control mandrel shaft and feed-screw rotation.

In order that the clutch mechanism may be operated from the handle 38, the latter is pro vided with a. manually operable button 52 conhected to the relatively moving parts 53 and 54 of a Bowden-wire 55, which passes through the speaking tube 3'7 rearwardly to the carriage 17, and from the latter downwardly to a boss 56 forming part of the housing 22, where the outside member 54 of the Bowden-wire is anchored. At this point, the inside member 53 of the Bowdenwire has a plunger 57 slidably moving in the boss 56 and having its front end in engagement with a bell-crank 58 pivoted at 59 as shown in Fig. 1, and having an arm 60 adapted to engage an arm 61 on the clutch shifting yoke 46. Thus, when the button 52 is depressed, the inner member 53 is moved relatively to the outer member 54 of the Bowden-wire and this in turn causes the plunger 57 to move the bell crank 58, which rocks the clutch shifting yoke 46, to start the machine as hereinbefore described. Upon the plunger 57 being retracted by the operation of the button 52, a spring 46' disposed between the yoke and the frame, as shown in Fig. 1, returns the yoke to its former position, at the same time releasing the clutch parts 50 and 51 and stopping the rotation of the machine.

In order to accomplish one of the principle objects of the present invention-namely that of making the operation of the machine simpler and more positive, the present invention provides means to lock the start-and-stop control against operation when the sound-box control is in neutral position and to automatically start or stop the machine operating when the sound-box control mousse is moved 3170 or from reproducing position respectively.

As shown in the accompanying drawings, this means may comprise a bolt 62 transversely mov able in the upper section of the housing 22 by operation of the related sound-box control in a mannadescribed below. With the sound-box control in recording position, the bolt 62 is posi- 'tioned relative to the clutch shitting yoke 46, as

shown in Figs; 3 and 5, and hence, locking lugs 63 .do not obstruct movement of the clutch shiIt-'.

ing yoke 46 to start andstop the machine.

However, when the sound-box control is moved 'rearwardly into neutral position, the locking lugs i ditioned to record, should he inadvertently attempt to do so.

. as to start the machine.

As stated above, the present invention also provides means for automatically starting the machine incidental to the movement of the condi-,

tioning control means to reproducing position.

While this may be accomplished in several ways within the scope of this invention, in the present .emlgloent it is extremely advantageous to use the bolt 62 to accomplish this result. Accordingly, the bolt 62 isprovidedwith oil-set or earn portions which actuate the clutch shifting yolre This is accomplished when the-sound-box control is moved rearwarto reproducing position, and the bolt 32, which it operates in a manner described below, is moved forwardly causing oil-set or cam portions oi j the bolt to slide in the apertures so, the ofiset portions o5 cumming the clutch sh fting yoke ior= wardly to the position shown in Figs. l and, 7, thus actuating the related clutch ll to start the machine.

By this arrangement, the operation ol the m chine is greatly simplified for the machine is automaticallystarted without attention from the dictator when the sound-box control is moved to reproducing position, and no other separate control meansneed be operated, as heretofore,

in order to start the machine.

To further, minimize the thought and efiort usu-' ally required to operate the machine, the present invention provides means for automatically returning the sound-box control from reproducing position to neutral position upon release 'oi the sound-box control lever by the onerator. This means, some tothe present embocnt, com

prises a spring or held on the carriage by screws to which spring forces the control lever S6 forwardly to the neutral position where its move ment is stopped by the free end oi the ones on abutment or stop soon the carriage.

Hence, in order to listen to matter recorded, the

operator merely moves the-sound-bon control lever so rearwardlv into reproducing position againstthe pressure oi the spring so and holds it in this position while liste. When he has heard all he desires, the operator removes his finger from the lever 36 and the sound-box control automatically .moves to neutral position under the influence of the spring 68. In tins position,

as statedabovegthe sta'rt-and-stop device is locked against operation and, before the operator can again depress the button 52 to start the machine for dictating, he must move the control lever to recording position.

As above stated, movement of'the bolt62 is controlled .by the control lever '36. The means for doing this, which it should-be noted includes 0 means whereby the bolt 62 may be operated by; the control lever 36 with the carriage in any position longitudinallyon the machine, will now be described. For this and other purposes, the present invention provides a ball .70 comprising the. cross-bar 70"and arms 71 and 72 mounted for arcuate movement about the axis of the carriage rod 15. .The arm 72 is provided at its lower end with a stud 73 which enters a slot 74 in the bolt 62 so that movement of the bail causes the bolt 00 to be slid forwardly orbackwardly, according to whether the ball 70 is rocked clockwise ,or countor-clockwise, as viewed in Fig. 2. It should be especially noted that with this construction the usual scale-bar may be used for the cross-bar 70', thereby providing a simple and advantageous construction for the purpose set forth;

To connect the ball '70 with the control lever 36 and yet permit longitudinal movement of the. carriage 1'? relative thereto, the control lever is provided with a notch 75 in which lies the crossbar to oi the ball 70. Since the bar 20' extends clear across the machineand slides in the notch 75, the control lever may be arcuately moved, at any time, irrespective of the location of the car- Ni riage longitudinally on the machine. I

When the control lever 36 is moved forwardly from neutral position to recording position, as viewed in Fig. 3, the bail to, through the connection '35, will be moved arcuately forward, rono toting, the arm 72 which, through theconnecting stud 73, moves the bolt 62 rearwardly to the position l y', as shown by dotted-lines in Fig. 2, at which time the relative positions of the bolt and clutch shifting yoke will be as shown in Figs. 3 Hi5 and 5.

Conversely, when the dontrol lever so is moved" rearwardly to the reproducing position, the ball.

70 is rotated rearwardly and the bolt 62 is moved forwardly to the position B as shown by dotted 112$ lines inf-Fig. 2, at which time the relativeposition oi the bolt and clutch shitting yoke will be as shown in l and 7.

To iurther iacilitate manipulation of the ma chine for rec'or, reproducing or to be neutral and operate the related bolt castes, present hi vention further provides a secondary control comprising an upwardly extending 7 6, preferix-:1: part of the arm 72, which can be operated in the samemanner as the control lever so. This leverhas a fined location longitudinally relative to the mace and, couently, the omrator need not consciously-observe the machine to locate the travelling control lever 36 in order to operate the machine, but may subconsciously locate and move the secondary control 76, the location oi which is constant. An arm is may, for conveniencebe located at the opposite end of the machine onthe lever '71 as shown, thus providing a control 0! constant location on no both ends 0! the machine and another traveling with the carriage. 0r, ii desired, either of these arms 76 or 76' be omitted. Further, it it is desired, the upwardly extending arm of the controlslever 36 on the traveling carriage may be dispensed with, whereupon the machine may be operated entirely by the-arms Wand id, or by either 01' them. i x

As shown in the accompanying drawings. the

electric motor tlssupplied with electric cur- 5 rent by a pair of wires '78, of which a lead wire '79 may be, as shown, connected directly with-the motor 43 and the other lead wire 80 connected with a switch 81, and from the switch a lead wire 82 carries the current to the motor to complete the circuit.

This switch is operated from a remote point on the machine and may, of course, be of any suitable type; but, as shown in Fig. '2, comprises contacts 83 and 84 connected to the leads 80 and 82 respectively, and the circuit is closed by movement of a plunger 85 downwardly, until a bridge 86 closes the gap between the contacts 83 and 84.

As usual, in order that the motor will be automatically stopped when the mouthpiece is placed on a supporting lever 8'7, the latter, which is pivoted on a stud 88, is pivotally connected at 89 with a vertically movable link 90 provided with an arm 91 which engages the switch plunger 85.-

The lever 90 is also provided with an extension 92, which passes through an aperture in the main frame where it is provided with a spring 93 which tends to force the link 90 downwardly to operate the plunger 85 and connect the switch to start the motor when the mouthpiece is taken from the supporting lever 8'7, yet allows upward movement of the link 90 and plunger when the mouthpiece is again placed on the lever 87.

To lock the supporting lever 87 against accidental displacement and thus hold the switch in o position when the machine is not in regular use, as at night, a. plunger 94 is slidably mounted in a stationary bracket 95 and is adapted to be moved into an aperture, indicated by the dotted circle 87 in Fig. 2, in the supporting lever 87 to hold it down.

In order to prevent the operator from dictating while the machine is inoperable, due to the switch lever being locked, the present invention provides means for locking the clutch mechanism. This means comprises an extension 98, part of the link 90 which extends through an aperture in the frame, and the top portion 9'! of which is located under a portion of the clutch shifting yoke. when the switch operating link 90 is, for any reason, in

' the of! position as shown in Fig. 2, as, for instance, when the supporting lever 87 is locked by the plunger 94, the top portion 97 of the extension obstructs pivotal movement of the clutch shifting yoke 46 and, consequently, the machine cannot be operated.

However, when the switch operating link 90 moves downwardly to the on, position, the top portion 97 of the extension moves downwardly sumciently to permit regular pivotal movement of the clutch-shifting yoke-46 to regularly start-and-stop the machine.
